SENIOR CONVERTIBLE NOTE

Issuance Date: December 31, 2007

Original Principal Amount: U.S. $[]

FOR VALUE RECEIVED, I-MANY, INC., a Delaware corporation (the Company),
hereby promises to pay to [HIGHBRIDGE INTERNATIONAL LLC] [PORTSIDE GROWTH AND OPPORTUNITY FUND] [STARBOARD VALUE AND OPPORTUNITY MASTER FUND LTD.] [PARCHE, LLC] [OTHER BUYERS] or registered assigns (the Holder) the amount
set out above as the Original Principal Amount (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the Principal) upon the Maturity Date (as defined below), and to pay interest
(Interest) on any outstanding Principal at a rate per annum equal to the Interest Rate (as defined below) from the date set out above as the Issuance Date (the Issuance Date) until the same becomes due and
payable, whether upon an Interest Date (as defined below), the Maturity Date, acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Senior Convertible Note (including all Senior Convertible Notes
issued in exchange, transfer or replacement hereof, this Note) is one of an issue of Senior Convertible Notes issued pursuant to the Securities Purchase Agreement on the Closing Date (collectively, the Notes and
such other Senior Convertible Notes, the Other Notes). Certain capitalized terms used herein are defined in Section 28.

(1) MATURITY. On the Maturity Date, the Company shall pay to the Holder an amount in cash
representing all outstanding Principal and accrued and unpaid Interest, if any. The Maturity Date is December 31, 2012.

(2) INTEREST; INTEREST RATE. (a) Interest on this Note shall commence accruing on the outstanding Principal on the Issuance Date and shall be computed on the basis of a 360-day year and twelve 30-day months and shall be payable
in arrears on March 31, June 30, September 30 and December 31 of each year (each, an Interest Date) with the first Interest Date being March 31, 2008. Interest shall be payable on each Interest
Date, to the record holder of this Note on the applicable Interest Date in cash.

(b) Prior to the payment of Interest on an Interest Date,
Interest on this Note shall accrue at the Interest Rate and be payable in cash. From and after the occurrence and during the continuance of an Event of Default, the Interest Rate shall be increased to ten percent (10.0%). In the event that such
Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance
of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and including the date of cure of such Event of Default.

(3) CONVERSION OF NOTES. This Note shall be convertible into shares of Common Stock, on the terms and conditions set forth in this Section 3.

(a) Conversion Right. Subject to the provisions of Section 3(e), at any time or times on or after the Issuance Date, the
Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and nonassessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined
below). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock
up to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount; provided that the
Company shall not be required to pay any tax that may be payable in respect of any issuance of shares of Common Stock to any Person other than the Holder.

(b) Conversion Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by
(y) the Conversion Price (the Conversion Rate).

(i) Conversion Amount means the
portion of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made.

(ii) Conversion Price means, as of any Conversion Date (as defined below) or other date of determination, $3.8192, subject to adjustment as provided herein.

(c) Mechanics of Conversion.

(i) Optional Conversion. To convert any Conversion Amount into shares of
Common Stock on any date (a Conversion Date), the Holder shall (A) transmit by facsimile (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice of conversion
in the form attached hereto as Exhibit I (the Conversion Notice) to the Company and (B) if required by Section 3(c)(iii), surrender this Note to a common carrier for delivery to the Company as soon as practicable
on or following such date (or an indemnification undertaking and appropriate bond with respect to this Note in the case of its loss, theft or destruction). On or before the first (1st) Trading Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile a confirmation of receipt of such Conversion Notice to the Holder and the Companys transfer agent
(the Transfer Agent). On or before the second (2nd) Trading Day following the date of receipt of a Conversion Notice (the
Share Delivery Date), the Company shall (1) (x) provided that the Transfer Agent is participating in the Depository Trust Companys (DTC) Fast Automated Securities Transfer Program, credit such
aggregate number of shares of Common Stock to which the Holder shall be entitled to the Holders or its designees balance account with DTC through its Deposit Withdrawal Agent Commission system or (y) if the Transfer Agent is not
participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common
Stock to which the Holder shall be entitled and (2) pay to the Holder in cash, by wire transfer of immediately available funds, an amount equal to the Additional Interest Amount, if any on the Conversion Amount subject to such conversion. If
this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as
practicable and in no event later than three (3) Trading Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note (in accordance with Section 17(d)) representing the outstanding Principal not
converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date.

(ii) Companys Failure to Timely Convert. If the Company is required to effect a conversion pursuant to
a Conversion Notice and the Company shall fail to issue a certificate to the Holder or credit the Holders balance account with DTC, as applicable, for the number of shares of Common Stock to which the Holder is entitled upon conversion of any
Conversion Amount on or prior to the date which is three (3) Trading Days after the Conversion Date (a Conversion Failure), then the Holder, upon written notice to the Company, may void its Conversion Notice with respect to,
and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to such Conversion Notice; provided that the voiding of a Conversion Notice shall not affect the Companys obligations to make
any payments which have accrued prior to the date of such notice pursuant to this Section 3(c)(ii) or otherwise. In the alternative to the voiding of the Conversion Notice, if within three (3) Trading Days after the Companys receipt
of the facsimile copy of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holders balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon
the Holders conversion of any Conversion Amount and if on

or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale to a third
party by the Holder of Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company (a Buy-In), then the Company shall, within three (3) Trading Days after the Holders request and in
the Holders discretion, either (x) pay cash to the Holder in an amount equal to the Holders total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the shares of Common Stock so purchased
(the Buy-In Price), at which point the Companys obligation to deliver shares of Common Stock with respect to the applicable Conversion Amount shall terminate, or (y) promptly honor its obligation to deliver to the
Holder the shares of Common Stock to which the Holder is entitled to have received upon the conversion of the applicable Conversion Amount and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of
(I) such number of shares of Common Stock, times (II) the Closing Bid Price on the Conversion Date.

(iii)
Registration; Book-Entry. The Company shall maintain a register (the Register) for the recordation of the names and addresses of the holders of each Note and the principal amount of the Notes held by such holders (the
Registered Notes). The entries in the Register shall be conclusive and binding for all purposes absent manifest error. The Company and the holders of the Notes shall treat each Person whose name is recorded in the Register as the
owner of a Note for all purposes, including, without limitation, the right to receive payments of Principal and Interest hereunder, notwithstanding notice to the contrary. A Registered Note may be assigned or sold in whole or in part only by
registration of such assignment or sale on the Register. Upon its receipt of a request to assign or sell all or part of any Registered Note by a Holder, the Company shall record the information contained therein in the Register and issue one or more
new Registered Notes in the same aggregate principal amount as the principal amount of the surrendered Registered Note to the designated assignee or transferee pursuant to Section 17. Notwithstanding anything to the contrary set forth herein,
upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Principal amount represented by this Note is being converted
or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain
records showing the Principal converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion.

(iv) Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes,
and the Company is required to effect conversions pursuant to such Conversion Notices, for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to
Section 3(e), shall convert from each holder of Notes electing to have Notes converted on such date a pro rata amount of such holders portion of its Notes submitted for conversion based on the principal amount of Notes submitted for
conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a
conversion of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 22.

- 4 -

(d) Mandatory Conversion.

(i) General. If at any time from and after December 31, 2009 (the Mandatory Conversion Eligibility Date),
(1) the Closing Sale Price of the Common Stock exceeds 200% of the Conversion Price on the Issuance Date (subject to appropriate adjustments for any stock dividend, stock split, stock combination, reclassification or similar transaction after
the Subscription Date) for each of any twenty (20) Trading Days occurring following the Mandatory Conversion Eligibility Date in any thirty (30) consecutive Trading Day period (such period, the Mandatory Conversion Measuring
Period) and (2) there is not then an Equity Conditions Failure, the Company shall have the right to require the Holder to convert all or any portion of the Conversion Amount then remaining under this Note, in each case as designated
in the Mandatory Conversion Notice (as defined below) into fully paid, validly issued and nonassessable shares of Common Stock in accordance with Section 3(c) hereof at the Conversion Rate as of the Mandatory Conversion Date (as defined below)
(a Mandatory Conversion). The Company may exercise its right to require conversion under this Section 3(d) by delivering a written notice thereof by facsimile and overnight courier to all, but not less than all, of the
holders of Notes and the Transfer Agent (the Mandatory Conversion Notice and the date all of the holders received such notice by facsimile is referred to as the Mandatory Conversion Notice Date) within two
(2) Business Days following the end of the applicable Mandatory Conversion Measuring Period. The Mandatory Conversion Notice shall be irrevocable. The Mandatory Conversion Notice shall (y) state (I) the Trading Day selected for the
Mandatory Conversion, which Trading Day shall be no sooner than twenty (20) Trading Days nor later than sixty (60) Trading Days following the Mandatory Conversion Notice Date (the Mandatory Conversion Date), (II) the
aggregate Conversion Amount of the Notes subject to Mandatory Conversion from the Holder and all of the holders of the Notes pursuant to this Section 3(d) (and analogous provisions under the Other Notes), (III) the number of shares of Common
Stock to be issued to the Holder on the Mandatory Conversion Date and (IV) the amount of accrued and unpaid Interest to be paid to the Holder in cash on the Mandatory Conversion Date and (z) certify that there has been no Equity Conditions
Failure.

(ii) Pro Rata Conversion Requirement. If the Company elects to cause a conversion of any Conversion Amount
of this Note pursuant to Section 3(d)(i), then it must simultaneously take the same action in the same proportion with respect to the Other Notes. If the Company elects a Mandatory Conversion of this Note pursuant to Section 3(d)(i) (or
similar provisions under the Other Notes) with respect to less than all of the Conversion Amounts of the Notes then outstanding, then the Company shall require conversion of a Conversion Amount from each of the holders of the Notes equal to the
product of (1) the aggregate Conversion Amount of Notes which the Company has elected to cause to be converted pursuant to Section 3(d)(i), multiplied by (2) the fraction, the numerator of which is the sum of the aggregate Original
Principal Amount of the Notes purchased by such holder (or the ultimate holder of a Note transferred as set forth below with an allocation among such Notes as set forth below) of outstanding Notes and the denominator of which is the sum of the
aggregate Original Principal Amount of the Notes purchased by all (or the ultimate holder of a Note transferred as set forth below with an allocation among such Notes as set forth below)

- 5 -

holders holding outstanding Notes (such fraction with respect to each holder is referred to as its Conversion Allocation Percentage, and
such amount with respect to each holder is referred to as its Pro Rata Conversion Amount); provided, however, that in the event that any holders Pro Rata Conversion Amount exceeds the outstanding Principal amount of such
holders Note, then such excess Pro Rata Conversion Amount shall be allocated amongst the remaining holders of Notes in accordance with the foregoing formula. In the event that the initial holder or any subsequent holder of any Notes shall sell
or otherwise transfer any of such holders Notes, the transferee shall be allocated a pro rata portion of such transferring holders Conversion Allocation Percentage and the Pro Rata Conversion Amount. For purposes of illustration of the
foregoing, the Conversion Allocation Percentage and Pro Rata Conversion Amount of any Note shall be calculated by reference to its Original Principal Amount and, in transferring any portion of the Note, or any subsequent Note evidencing some or all
of the Principal payable on this Note, the allocated Original Principal Amount shall be indicated thereon, and shall not be reduced by any payment or conversion thereof.

(e) Limitations on Conversions.

(i) Beneficial Ownership. Other than in connection with a Mandatory Conversion, [INSERT ONLY IN RAMIUS NOTES: at such time as the Holder (including any of the Holders affiliates) does not have a representative on the
Companys board of directors and the beneficial ownership of the Holder (together with its affiliates), without giving effect to Conversion Shares issuable hereunder, is not in excess of 9.99%,]1 the Company shall not effect any conversion of this Note, and the Holder of this Note shall not have the right to convert any portion
of this Note pursuant to Section 3(a), to the extent that after giving effect to such conversion, the Holder (together with the Holders affiliates) would beneficially own in excess of [4.99%]2[9.99%]3 (the Maximum Percentage) of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the number of shares of
Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of Common Stock issuable upon conversion of this Note with respect to which the determination of such sentence is being made, but shall exclude the
number of shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Note beneficially owned by the Holder or any of its affiliates and (B) exercise or conversion of the unexercised or
nonconverted portion of any other securities of the Company (including, without limitation, any Other Notes) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of
its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 3(d)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the
Exchange Act). For purposes of this Section 3(d)(i), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the
Companys most recent Form 10-K, Form 10-Q, Form 8-K or other public filing with the SEC, as the case may be, (2) a more recent

public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock
outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any
case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder or its affiliates since the date as of which such number of
outstanding shares of Common Stock was reported. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3(e)(i) to correct this paragraph (or any
portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. By written notice to the
Company, the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (x) any such increase or decrease will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and (y) any such increase or decrease will apply only to the Holder and not to any other holder
of Notes.

(ii) Market Regulation. The Company shall not be obligated to issue any shares of Common Stock upon
conversion of this Note if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion of the Notes without breaching the Companys obligations under the
rules or regulations of the Principal Market whether or not the Common Stock is listed on the Principal Market (the Exchange Cap), except that such limitation shall not apply in the event that the Company (A) obtains the
approval of its stockholders as required by the applicable rules of such Principal Market for issuances of Common Stock in excess of such amount or (B) obtains a written opinion from outside counsel to the Company that such approval is not
required, which opinion shall be satisfactory to the Majority Holders. Until such approval or written opinion is obtained, no purchaser of the Notes pursuant to the Securities Purchase Agreement (the Purchasers) shall be issued in
the aggregate, upon conversion of Notes, shares of Common Stock in an amount greater than the product of the Exchange Cap multiplied by a fraction, the numerator of which is the principal amount of Notes issued to a Purchaser pursuant to the
Securities Purchase Agreement on the Closing Date and the denominator of which is the aggregate principal amount of all Notes issued to the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser,
the Exchange Cap Allocation). In the event that any Purchaser shall sell or otherwise transfer any of such Purchasers Notes, the transferee shall be allocated a pro rata portion of such Purchasers Exchange Cap
Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee and such allocation and restriction shall apply to all successive
transferees, ratably in accordance with their respective interest in the Original Principal Amount evidenced by their Notes. In the event that any holder of Notes shall convert all of such holders Notes into a number of shares of Common Stock
which, in the aggregate, is less than such holders Exchange Cap Allocation, then the difference between such holders Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder shall be allocated to
the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in proportion to the aggregate principal amount of the Notes then held by each such holder.

- 7 -

(f) Conversion Upon Fundamental Change. The conversion by the Holder following its receipt of a
Change of Control Notice during the Change of Control Conversion/Redemption Period shall be a Change of Control Conversion. In connection with a Change of Control Conversion, the Holder shall be entitled to receive the Make-Whole
Premium with respect to any Conversion Amount converted in accordance with Section 3(c).

(4) RIGHTS UPON EVENT OF DEFAULT.

(a) Event of Default. Each of the following events shall constitute an Event of Default:

(i) the suspension from trading or failure of the Common Stock to be listed on an Eligible Market for a period of five
(5) consecutive Trading Days or for more than an aggregate of ten (10) Trading Days in any 365-day period;

(ii)
the Companys (A) failure to cure a Conversion Failure by delivery of the required number of shares of Common Stock or Make-Whole Premium within ten (10) Business Days after the applicable Conversion Date or Change of Control
Settlement Date (as defined in Section 9(a)), as the case may be, or (B) notice, written or oral, to any holder of the Notes, including by way of public announcement or through any of its agents, at any time, of its intention not to comply
with a request for conversion of any Notes into shares of Common Stock that is tendered in accordance with the provisions of the Notes, other than pursuant to Section 3(e);

(iii) at any time following an Authorized Share Failure Deadline if there has been an Authorized Share Failure;

(iv) the Companys failure to pay to the Holder any amount of Principal, Interest or other amounts when and as due under this Note
(including, without limitation, the Companys failure to pay any redemption amounts hereunder) or any other Transaction Document (as defined in the Securities Purchase Agreement) or any other agreement, document, certificate or other instrument
delivered in connection with the transactions contemplated hereby and thereby to which the Holder is a party, except, in the case of a failure to pay Interest when and as due, in which case only if such failure continues for a period of at least
seven (7) Business Days;

(v) any redemption of or acceleration prior to maturity of any Indebtedness exceeding
$1,000,000 individually or in the aggregate of the Company or any of its Subsidiaries other than with respect to any Other Notes;

(vi) the Company or any of its Significant Subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, or any similar Federal, foreign or state law for the relief of debtors (collectively, Bankruptcy Law),
(A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a receiver, trustee, assignee, liquidator or similar official (a
Custodian), (D) makes a general assignment for the benefit of its creditors or (E) admits in writing that it is generally unable to pay its debts as they become due;

- 8 -

(vii) a court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that (A) is for relief against the Company or any of its Significant Subsidiaries as debtor in an involuntary case, (B) appoints a Custodian of the Company or any of its Significant Subsidiaries or (C) orders the liquidation of
the Company or any of its Significant Subsidiaries;

(viii) a final judgment or judgments for the payment of money
aggregating in excess of $2,000,000 are rendered against the Company or any of its Subsidiaries and which judgments are not, within sixty (60) days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged
within sixty (60) days after the expiration of such stay; provided, however, that any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating the $2,000,000 amount set forth above
so long as the Company provides the Holder a written statement from such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity
and the Company will receive the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment;

(ix) other than as specifically set forth in another clause of this Section 4(a), the Company breaches, in any material respect, any material representation, warranty, covenant or agreement in any Transaction
Document, except, in the case of a breach of a covenant or agreement in any Transaction Document which is curable, only if such breach continues for a period of at least thirty (30) consecutive days;

(x) any breach or failure in any respect to comply with either of Sections 8 or 13 of this Note; or

(xi) any Event of Default (as defined in the Other Notes) occurs with respect to any Other Notes, unless such Event of Default is waived
or cured.

(b) Acceleration and Redemption. Upon the occurrence of an Event of Default with respect to this Note or any Other Note,
the Company shall within one (1) Business Day deliver written notice thereof via facsimile and overnight courier (an Event of Default Notice) to the Holder and the Other Holders. If an Event of Default other than an Event of
Default specified in Section 4(a)(vi) or (vii) occurs, the Required Holders, at any time after the earlier of the Holders or any Other Holders receipt of an Event of Default Notice and the Holder or any Other Holders
becoming aware of an Event of Default, by one or more written notices to the Company, may declare the entire Conversion Amount of all of the Notes plus accrued and unpaid Interest thereon due and payable immediately and upon any such declaration
such Conversion Amount of all the Notes plus accrued and unpaid Interest thereon shall become immediately due and payable. Notwithstanding the foregoing, in the case of an Event of Default specified in Section 4(a)(vi) or (vii), the Conversion
Amount of all of the Notes plus accrued and unpaid Interest thereon will ipso facto become due and payable without any declaration or other act on the part of the Holder or any of the Other Holders. Upon an acceleration in accordance with the
preceding sentence or upon an Event of Default specified

- 9 -

in Section 4(a)(vi) or (vii) occurs, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice
thereof (the Event of Default Redemption Notice) to the Company, which Event of Default Redemption Notice shall indicate the Conversion Amount of this Note the Holder is electing to require the Company to redeem. Each portion of
this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price (the Event of Default Redemption Price) equal to the sum of (i) the Conversion Amount to be
redeemed and (ii) any accrued and unpaid Interest thereon. Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 9. To the extent redemptions required by this Section 4(b) are deemed
or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments.

(c) Waiver of Past Defaults. The Majority Holders may on behalf of the Holders of all the Notes waive any past Event of Default hereunder and its consequences, except an Event of Default (i) specified in
Section 4(a)(vi) or (vii); or (ii) in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each Note affected. Upon any such waiver, such Event of Default shall cease to exist,
and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of the Notes; but no such waiver shall extend to any subsequent or other Event of Default or impair any right consequent thereon.

(d) Recission and Annulment. At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the
money due has been obtained by the Holder or any of the Other Holders, the Majority Holders, by written notice to the Company, may rescind and annul such declaration and its consequences if such rescission and annulment will not conflict with any
judgment or decree of a court of competent jurisdiction and (i) the Company has paid to the Holder and each Other Holder a sum sufficient to pay (A) all overdue Interest on the Notes, and (B) the Principal Amount plus accrued and
unpaid Interest, if any, any Redemption Price on any Notes which have become due otherwise than by such declaration of acceleration; and (ii) all Events of Default, other than the non-payment of Principal plus accrued and unpaid interest on
Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 4(c) above . No such rescission shall affect any subsequent default or impair any right consequent thereon.

(5) RIGHTS UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL.

(a) Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity expressly assumes in writing,
executed and delivered to the Holder concurrently with the consummation of the Fundamental Transaction, all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of this
Section 5(a) prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor Entity evidenced by a written instrument substantially similar in form and
substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts and the interest rates of the Notes then outstanding held by such holder, having similar conversion rights, with the
Conversion Rate adjusted to reflect the consideration received by the Companys stockholders in such Fundamental Transaction, and having similar ranking to the Notes. In furtherance of and not in limitation of the foregoing, prior to the
consummation of any Fundamental Transaction pursuant to

- 10 -

which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a
Corporate Event), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion of this Note, the shares of Common Stock receivable upon such conversion or such
securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the Holder upon the consummation of such Corporate Event (without taking into account
any limitations or restrictions on the convertibility of this Note). Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction,
the provisions of this Note referring to the Company shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note with the same
effect as if such Successor Entity had been named as the Company herein. If the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market (a
Public Successor Entity) and the consideration paid to holders of Common Stock in such Fundamental Transaction consists of stock in such Public Successor Entity (a Public Fundamental Transaction), then upon
consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of the Fundamental Transaction, in
lieu of the shares of the Companys Common Stock issuable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares of the publicly traded common stock (or their equivalent) of the Successor Entity
(including its Parent Entity), as adjusted in accordance with the provisions of this Note. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations
on the conversion or redemption of this Note.

(b) Redemption Right. No sooner than fifteen (15) days nor later than ten
(10) days prior to the consummation of a Change of Control, but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a
Change of Control Notice) which shall state:

(i) the events causing a Change of Control and the
anticipated Effective Date;

(ii) the last date of the Change of Control Conversion/Redemption Period (as defined below) by
which the Holder must deliver a Change of Control Redemption Notice to elect the redemption option pursuant to this Section 5(b) or deliver a Conversion Notice requesting conversion upon a Change of Control in accordance with Section 3(c);

(iii) the Change of Control Settlement Date;

(iv) the Change of Control Redemption Price;

(v) the Conversion Price applicable on the date of the Change of Control Notice;

(vi) that
Notes may be converted in connection with the Change of Control;

- 11 -

(vii) that the Change of Control Redemption Price for any Convertible Note as to which a
Change of Control Redemption Notice has been duly given will be paid promptly on the Change of Control Settlement Date; and

(viii) if the Holder is entitled to receive a Make-Whole Premium upon any conversion occurring within the Change of Control Conversion/Redemption Period.

At any time during the period beginning after the Holders receipt of a Change of Control Notice and ending twenty (20) Business Days after the Effective Date (such period, the Change of Control Conversion/Redemption
Period), the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (Change of Control Redemption Notice) to the Company, which Change of Control Redemption Notice
shall indicate the Conversion Amount the Holder is electing to require the Company to redeem. The portion of this Note subject to redemption pursuant to this Section 5(b) shall be redeemed by the Company in cash at a price (the Change
of Control Redemption Price) equal to the sum of (i) the Conversion Amount and (ii) any accrued and unpaid Interest thereon. Redemptions required by this Section 5 shall be made in accordance with the provisions of
Section 9 and shall have priority to payments to stockholders in connection with a Change of Control. To the extent redemptions required by this Section 5(b) are deemed or determined by a court of competent jurisdiction to be prepayments
of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5, but subject to Section 3(e), until the Change of Control Redemption Price (together with
any interest thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 5(c) (together with any Interest thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3
(and any such conversions shall be deemed to be a withdrawal of the Change of Control Redemption Notice to the extent of such conversion) and shall be entitled to receive the Make-Whole Premium upon any such conversion.

(c) Make-Whole Premium. (i) If a Change of Control occurs, the Company shall pay the Make-Whole Premium to the holders of the Notes who
effect a Change of Control Conversion at any time during the Change of Control Conversion/Redemption Period.

(A) The
Make-Whole Premium shall be equal to an additional number of shares of Common Stock calculated in accordance with this Section 5(c). The Make-Whole Premium will be in addition to, and not in substitution for, any cash, securities or other
assets otherwise due to the Holder upon conversion as described in this Note.

(B) The Make-Whole
Premium shall be equal to the Conversion Amount of the Notes to be converted divided by $1,000 and multiplied by the applicable number of shares of Common Stock determined by reference to the table below (the Make-Whole Premium
Table) and is based on the Effective Date and the Stock Price.

(C) The exact Stock Price and Effective Date may not be set forth on the Make-Whole
Premium Table, in which case, if the Stock Price is between two Stock Prices on the Make-Whole Premium Table or the Effective Date is between two Effective Dates on the Make-Whole Premium Table, the Make-Whole Premium shall be determined by
straight-line interpolation between Make-Whole Premium amounts set forth for the higher and lower Stock Prices and the two Effective Dates, as applicable, based on a 365-day year (or a 366-day year if the Effective Date occurs in a leap year). The
Stock Prices set forth in the column headers are subject to adjustment pursuant to Section 5(c)(iii).

(1) If the
Stock Price is less than or equal to $2.25 (subject to adjustment pursuant to Section 5(c)(iii), the Stock Price Threshold), the Make-Whole Premium shall be equal to zero shares of Common Stock.

(2) If the Stock Price is equal to or greater than $9.00 (subject to adjustment pursuant to Section 5(c)(iii), the Stock
Price Cap), the Make-Whole Premium shall be equal to zero shares of Common Stock.

(3) Stock
Price means the price paid per share of Common Stock in the transaction constituting the Change of Control, determined as follows: (i) if holders of Common Stock receive only cash in the transaction constituting the Change of Control,
the Stock Price shall equal the cash amount paid per share of Common Stock; and (ii) in all other cases, the Stock Price shall equal the arithmetic average of the Weighted Average Price of a share of Common Stock over the five Trading Day
period ending on the Trading Day immediately preceding the Effective Date; and Effective Date means the date that a Change of Control becomes effective.

(ii) The Company shall pay the Make-Whole Premium solely in shares of Common Stock (with any fractional shares rounded up to the nearest whole share) or
in the same form of consideration into which all or substantially all of the shares of Common Stock have been converted or exchanged in connection with the Change of Control. If holders of the Common Stock receive or have the right to receive more
than one form of consideration in connection with such Change of Control, then, for purposes of the foregoing, the forms of consideration in which the Make-Whole Premium shall be paid shall be in proportion to the different forms of consideration
paid to holders of Common Stock in connection with such Change of Control.

(iii) Whenever the Conversion Price shall be adjusted from
time to time by the Company pursuant to Section 7, the Stock Price Threshold and the Stock Price Cap shall be adjusted and each of the Stock Prices set forth in the Make-Whole Premium Table shall be adjusted (rounded to the nearest cent) in the
same manner and at the same time. Each of the share amounts set forth in the body of the Make-Whole Premium Table shall also be adjusted at the same time by multiplying the share amounts set forth in the body of the Make-Whole Premium Table by a
fraction, the numerator of which is the Conversion Price immediately prior to such adjustment and the denominator of which is the Conversion Price as so adjusted.

(6) RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS. If at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock,

- 14 -

warrants, securities or other property pro rata to the record holders of any class of Common Stock (the Purchase Rights), then the Holder
will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of
this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is
taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

(7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

(a) Adjustment of Conversion Price upon Subdivision or Combination of
Common Stock. If the Company at any time on or after the Subscription Date subdivides (by any stock dividend, stock split, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of
shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time on or after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more
classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased.

(b) Voluntary Decrease. The Company may at any time during the term of this Note reduce the then current Conversion Price to any amount and for
any period of time deemed appropriate by the Companys board of directors.

(8) OPTIONAL REDEMPTION BY COMPANY OR HOLDER.

(a) Optional Redemption by the Company. On and after December 31, 2010 (such date, the Triggering Optional Redemption
Date), the Company shall have the right, in its sole discretion, to redeem all or any portion of the Note (a Company Optional Redemption). In order for the Company to exercise the Company Optional Redemption at any time
on or after the Triggering Optional Redemption Date, the Company shall deliver written notice by confirmed facsimile and overnight courier to all, but not less than all, of the holders of the Notes (the Company Optional Redemption
Notice and the date such notice is delivered to all the holders is referred to as the Company Optional Redemption Notice Date) no later than twenty (20) Trading Days prior to the Company Optional Redemption Date (as
hereafter defined) which shall (w) state the date on which the Company Optional Redemption shall occur (such date, the Company Optional Redemption Date), the (x) describe the redemption rights provided in this
Section 8, (y) set forth the Optional Redemption Price, and (z) state the aggregate Principal of the Notes which the Company has elected to be subject to such Company Optional Redemption from all of the holders of the Notes pursuant
to this Section 8(b) (and analogous provisions under the Other Notes) plus accrued and unpaid Interest thereon (the Company Redemption Amount). The portion of this Note subject to redemption pursuant to this Section 8(a)
shall be redeemed by the Company in cash at a price (the Optional Redemption Price) equal to the sum of (x) the Conversion Amount being redeemed and (y) any accrued and unpaid Interest on the Conversion Amount. The
Company Optional Redemption Notice shall be irrevocable. Notwithstanding anything to the contrary in this Section 8, but subject to Section 3(e), until the Holder receives the Optional Redemption Price, the Conversion Amount reflected in
such Optional Redemption Notice may be converted, in whole or in part, by the Holder into Common

- 15 -

Stock pursuant to Section 3 (and any such conversions shall be deemed to be a withdrawal of the Company Optional Redemption Notice to the extent of such
conversion), and any such conversion shall reduce the Conversion Amount reflected in such Optional Redemption Notice. The Company Redemption Amount which is to be paid to the Holder on the applicable Company Optional Redemption Date shall be
redeemed by the Company, and the Company shall pay to the Holder on such Company Optional Redemption Date by wire transfer of immediately available funds, the Optional Redemption Price.

(b) Optional Redemption by the Holder. No later than twenty (20) Trading Days prior to the Triggering Optional Redemption Date, the Company
shall deliver written notice by confirmed facsimile and overnight courier to all, but not less than all, of the holders of the Notes (the Company Notice) which shall describe the redemption rights provided in this Section 8.
On the Triggering Optional Redemption Date, the Holder shall have the right, in its sole discretion, to require that the Company redeem all or any portion of the Note (a Holder Optional Redemption). In order for the Holder to
exercise its Holder Optional Redemption Right, the Holder must deliver written notice (the Holder Optional Redemption Notice) to the Company no later than five (5) Business Days prior to the later of (x) the Triggering
Optional Redemption Date and (y) twenty (20) Trading Days following the receipt of the Company Notice (such later date, the Holder Optional Redemption Date). The Holder Optional Redemption Notice shall indicate the
Conversion Amount the Holder is electing to have redeemed (the Holder Optional Redemption Amount) on the Holder Optional Redemption Date, which date shall be no earlier than the Triggering Optional Redemption Date and no later
than twenty (20) Trading Days following receipt of the Company Notice. The portion of this Note subject to redemption pursuant to this Section 8 shall be redeemed by the Company in cash at the Optional Redemption Price. Notwithstanding
anything to the contrary in this Section 8, but subject to Section 3(e), until the Holder receives the Optional Redemption Price, the Holder Optional Redemption Amount may be converted, in whole or in part, by the Holder into Common Stock
pursuant to Section 3 (and any such conversions shall be deemed to be a withdrawal of the Holder Optional Redemption Notice to the extent of such conversion), and any such conversion shall reduce the Conversion Amount reflected in such Optional
Redemption Notice. The Holder Optional Redemption Amount which is to be paid to the Holder on the applicable Holder Optional Redemption Date shall be redeemed by the Company, and the Company shall pay to the Holder on such Holder Optional Redemption
Date by wire transfer of immediately available funds, the Optional Redemption Price.

(c) Pro Rata Redemption Requirement. If the
Company elects to cause a Company Optional Redemption pursuant to Section 8, then it must simultaneously take the same action with respect to the Other Notes. If the Company elects to cause a Company Optional Redemption pursuant to this
Section 8 (or similar provisions under the Other Notes) with respect to less than all of the principal amount of the Notes then outstanding, then the Company shall require redemption of a Principal amount from the Holder and each holder of the
Other Notes equal to the product of (i) the aggregate principal amount of Notes which the Company has elected to cause to be redeemed pursuant to Section 8, multiplied by (ii) the fraction, the numerator of which is the sum of the
initial principal amount of Notes purchased by such holder (or the ultimate holder of a Note transferred as set forth below with an allocation among such Notes as set forth below) and the denominator of which is the initial principal amounts of
Notes purchased by all holders (or the ultimate holder of a Note transferred as set forth below with an allocation among such Notes as set forth below) holding outstanding Notes (such fraction with respect to each holder is referred to as its
Redemption

- 16 -

Allocation Percentage, and such amount with respect to each holder is referred to as its Pro Rata Redemption Amount);
provided that in the event that the initial holder of any Notes has sold or otherwise transferred any of such holders Notes, the transferee shall be allocated a pro rata portion of such transferring holders Redemption Allocation
Percentage and Pro Rata Redemption Amount; and provided further, that in the event any holders Pro Rata Redemption Amount exceeds the outstanding principal amount of such holders Note, any excess redemption amount shall be applied to the
principal amount of all remaining Notes on a pro rata basis pursuant to this subsection (b).

(d) Redemptions Generally. Any
redemptions made pursuant to this Section 8 shall be made in accordance with Section 9. No later than one (1) Trading Day following any Optional Redemption Date or Holder Optional Redemption Date, the Company shall file a Current
Report on Form 8-K describing the terms of such Holder Optional Redemption or Company Optional Redemption, as the case may be. To the extent redemptions required by this Section 8 are deemed or determined by a court of competent jurisdiction to
be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments.

(9) REDEMPTIONS.

(a) Mechanics. The Company shall deliver the applicable Event of Default Redemption Price to the Holder within five
(5) Business Days after the Companys receipt of the Holders Event of Default Redemption Notice. If the Holder has submitted a Change of Control Redemption Notice in accordance with Section 5(b), the Company shall deliver the
applicable Change of Control Redemption Price to the Holder (i) concurrently with the consummation of such Change of Control if such notice is received prior to the consummation of such Change of Control and (ii) within five
(5) Business Days after the Companys receipt of such notice otherwise (the Change of Control Settlement Date). The Company shall deliver the applicable Optional Redemption Price on the Optional Redemption Date or Holder
Optional Redemption Date, as applicable. In the event of a redemption of less than all of the Conversion Amount of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with
Section 17(d)) representing the outstanding Principal which has not been redeemed. In the event that the Company does not pay the applicable Redemption Price to the Holder within the time period required, at any time thereafter and until the
Company pays such unpaid Redemption Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder all or any portion of this Note representing the Conversion Amount that was submitted
for redemption and for which the applicable Redemption Price has not been paid. Upon the Companys receipt of such notice, (x) the applicable Redemption Notice shall be null and void with respect to such Conversion Amount and (y) the
Company shall immediately return this Note, or issue a new Note (in accordance with Section 17(d)) to the Holder representing such Conversion Amount.

(b) Redemption by Other Holders. Upon the Companys receipt of notice from any of the holders of the Other Notes for redemption or repayment as a result of an event or occurrence described in
Section 4(b), Section 5(b) or Section 8 (each, an Other Redemption Notice), the Company shall immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by facsimile a
copy of such notice. If there has been an Acceleration to the extent required and the Company receives a Holders Redemption Notice and one or more Other Redemption Notices, during the seven (7) Business Day period beginning on and
including the date which is three (3) Business Days prior to the Companys receipt of the Holders Redemption Notice

- 17 -

and ending on and including the date which is three (3) Business Days after the Companys receipt of the Holders Redemption Notice and the
Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice and such Other Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata amount
from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven Business Day
period.

(10) NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate
of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note.

(11) RESERVATION OF AUTHORIZED SHARES.

(a) Reservation. The Company shall initially reserve out of its authorized and unissued Common Stock a number of shares of Common Stock for each of the Notes equal to the Conversion Rate for each of the Notes as of the Issuance Date
plus the maximum number of shares of Common Stock issuable as a Make-Whole Premium under each of the Notes as of the Issuance Date. So long as any of the Notes are outstanding, the Company shall take all action necessary to reserve and keep
available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Notes
then outstanding and the maximum number of shares of Common Stock issuable as a Make-Whole Premium upon conversion of all outstanding Notes; provided that at no time shall the number of shares of Common Stock so reserved be less than the number of
shares required to be reserved by the previous sentence (without regard to any limitations on conversions) (the Required Reserve Amount). The initial number of shares of Common Stock reserved for conversions of the Notes and each
increase in the number of shares so reserved shall be allocated pro rata among the holders of the Notes (or the ultimate holder of a Note transferred as set forth below with an allocation among such Notes as set forth below) based on the principal
amount of the Notes held by each holder (or the ultimate holder of a Note transferred as set forth below with an allocation among such Notes as set forth below) at the Closing (as defined in the Securities Purchase Agreement) or increase in the
number of reserved shares, as the case may be (the Authorized Share Allocation). In the event that a holder shall sell or otherwise transfer any of such holders Notes, each transferee shall be allocated a pro rata portion of
such transferring holders Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount
of the Notes then held by such holders.

(b) Insufficient Authorized Shares. If at any time while any of the Notes remain
outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the
Required Reserve Amount (an Authorized Share Failure), then the Company shall immediately take all action necessary to increase the Companys authorized shares of Common Stock to an amount sufficient to allow the Company to

- 18 -

reserve the Required Reserve Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after
the date of the occurrence of an Authorized Share Failure, but in no event later than thirty (30) days after the occurrence of such Authorized Share Failure, the Company shall file a proxy statement with respect to a meeting of its stockholders
for the approval of an increase in the number of authorized shares of Common Stock and the Company shall be required to increase the number of authorized shares no later than ninety (90) days after the occurrence of the Authorized Share Failure
(the Authorized Share Failure Deadline). In connection with such meeting, the Company shall provide each stockholder with such proxy statement and shall use its best efforts to solicit its stockholders approval of such
increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal.

(12) VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law, including, but not limited to, the General Corporation Law of the State of Delaware, and as expressly provided in this
Note.

(13) COVENANTS.

(a) Ranking. All obligations evidenced by this Note and the Other Notes shall constitute senior obligations of the Company and are senior in right of payment to any existing or future subordinated indebtedness or other subordinated
obligations of the Company.

(b) Incurrence of Indebtedness. So long as this Note is outstanding, (i) the Company shall not,
directly or indirectly, incur or guarantee, assume or suffer to exist any Indebtedness, other than Permitted Indebtedness and (ii) the Company shall not permit any of its Subsidiaries to, directly or indirectly, incur or guarantee, assume or
suffer to exist any Indebtedness, other than Permitted Pari Passu Indebtedness and Indebtedness secured by Permitted Liens.

(c)
Existence of Liens. So long as this Note is outstanding, the Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, allow or suffer to exist any mortgage, lien, pledge, charge, security
